A ROLL-PAPER CQNTROLLER.

Application filed October 3, 1921. Serial No. 504,962.

70 all whom 'if 'may cof/wem Be it known that I, GEORGE BULLOCK, acitizen of the United States, residing at Grand Junction, Mesa County,Colorado,

Ahave invented a new and useful Roll-Paper Cont-roller, of which thefollowing is a speci- (ication.

This invention troller. 1

It is now the usual. practice to support a roll of wrapping paperl in aframe provided with a bladeA that is pressed against the paper roll byan actuating device, such 'as a spring' or a weight. The paper is tornoff along the edge of the blade so that when it is again desired to takepaper from the roll relates to a roll paper con- `it isnecessary to turnthe roll a distance by hand before the edge of the paper can 'beengaged. This present construction also admits of the paper being takenfrom only one side of the roll.

The blade aga-inst which the paper is torn serves well `enough to clampthe paper to permit it to be torn off when the roll is full or large;but as the paper is taken from the roll and the size of the rolldiminishes the clamping effect of the blade against the roll islessened, often with 'the result that' the paper will be torn unevenlysince the pres sure of the blade is not suliicient to hold the paperfirmly While the paper is being torn.

An object of the present invention isto provide an improved rollpapercontroller' in which after each piece of paper is torn off, a sufficientportion of the paper is left for easy manual engagement `when it f isagain desired to take paper from the roll.

Another object of the invention is to provide an improved roll papercontroller in which the paper can be taken toward either side with equalfacility and in ywhich a sufficient portion of the paper is leftprojecting free from the clamping device for manual engagement.

Another object of the invention is to provide an improved roll papercontroller in which the paper will be firmly clamped and held when apiece of paper is being torn oif for use, irrespective of the size ofthe roll or the amount of paper on the roll.4

Another object of the invention is to pro-` vide an improved roll paper'controller overcoming all of the objections above mentionec.

(ther objects ofthe invention will appear from the followingdescription, reference being made to the drawing, in which .if l is aside elevation of a rollpaper controller embodying my present invention.

2 is a vertical sectional view on the 60 line 2`2 of Fig. l'.

In the embodiment of the invention shown the two upright standards l aresecured in proper position relative to each other and may have theirupper ends connected by the cross or tie member 2, A roll 3 of paper issupported between the uprights l upon an support e. The ends of theaxial support 1l extend into vertical slot-s 5 in the uprights lpermitting downward movement of the paper roli asthe paper is taken offand the size or diameter of the roll diminishes. n A smaller roll 6 hasaxial extensions 7 on its oppositie ends extending into short slots S inthe uprights l. The slots 8 are at one 75 side of the vertical plane ofthe axis of the support 4; so that the pressure of the paper roll 3 uponthe roller 6 actuates said roller outwardly until the axial members 7are at the outer ends of the slots 8. This is because the weight of thepaper roll 3 imparts a lateral pressure upon the roll 6, due to theposition of said -roller at one side of the rvertical plane of the axisofthe paper roll.`

A pivoted clamp and tear device is supported at one side of the roller6. As shown, said device comprises a plate 9 having ears l0 extendingfrom the opposite ends thereof and pivoted upon supports l1 inconnection with the uprights l. The inner edge of the plate 9 isprovided with an up-turned fiange 12 located adjacent to and curving insubstantial conformity with the curvature of the surface of the vrollerG. The paper from the paper roll 8 is passed downwardly 95 between theroller 6 andthe flange l2. The endV of the paper hangs down a sutiicientdistance for convenient manual engagement from either side of the paperroll so that the paper may be drawn in either direction. The outer edgeof the plate 9 is formed with a downwardly turned flange 13. When thcl isupports 17 in 'from that side of the device. ledge ofl the plate 15 hasan up-turned flange 19 curving approximately to the curvature ofthesurface of the roller 6 and arranged paper is drawn out a sufiicientdistance for the piece of paper desired it is raised against and tornalong the flange 13. As the paper is raised and torn the outer edge ofthe plate 9 is raised and the flange 12 is pressed or clamped againstthe paper between said flange and the roller 6. By this clamping actionthe paper is held from further movement so that the paper will be tornstraight across along the edge of the flange 13.

After the piece of paper has beenvtorn off the free edge of the paperdrops down so that it can be conveniently engaged from either side ofthe paper roll. The outer portion of theplate 9 is normally sustainedbysupporting lugs or projections 14 in connection with the uprights 1. Thelugs A14 do not interfere with the clamping action of the device.

A plate 15, having ears 16 pivoted upon connection with the uprights 1,is supported at the opposite side of the roller 6 from the plate 9. Thewidth of the plate 15 added to the diameter of the roller 6 is the same,or approximately the same,

fas the width 'of-the plate 9 so that about the same length of paperwill be left extending below the roller 6 for manual engage- Ament,irrespective of the side at which the paper is torn off. The outer edgeof the plate 15 has a down-turned flange 18 along which the paper `willbe torn when taken The inner to press against the roller 6 when theouter portion ofthe plate 15 is raised by4 tearing the paper along theflange 18. The pressure of the flange 19 against the roller 6 forces-theroller 6 over against the flange 12, causing the paper to be clampedbetween the roller and said flange. This holds the paper so that thepaper will be torn straight across along a line 'definedby the edge ofthe flange 1S. Normally the outer portion of the plate 15 is supportedby lugs or projections 2O in connection with the uprights 1.

The lower edges of the flanges 13 and 18 may be formed with teeth ornot, as desired. If the flanges are formed with teeth for `puncturingthe paper, the paper may be separated more easily and with less pressurethan otherwise.

From the foregoing it is apparent that my invention obtains all of itsintended objet/cs in a highly convenient, efiicient and simple manner.There is always sufficient paper left for easy manual engagement,irrespective of the side from which the paper is taken and the paper maybe taken from either side of' the paper roll with equal facility.

The clampingdevice is effective to hold'l desired and as are within thescope of the appended claims.
